Risk Assessment: Engineering Tool
In factoring in human-health impacts when tackling an environmental problem, risk assessment is often the best approach. Its use is growing fast. The technique increasingly is being used...
Dynamics of Fender and Rack Systems for Docking Ferries
A dynamic analysis of a ferry fender and rack system is developed based on the conservation of energy principle and Newton's laws of motion. The dynamics of the interaction...
Floating Bridges in Short-Crested Random Seas
Four large concrete floating bridges located in Washington State have been the subject of extensive analytical modeling for dynamic response to storm waves. The dynamic analysis of the...
Diffraction Forces on Axisymmetric Bodies
Use of a Green function satisfying the governing differential equation and all boundary conditions except those on the boundary of the structure yields an integral equation, when these...
Disney Engineers Voyage to the Deep
The main show at the Living Seas Pavilion, part of Walt Disney Production's EPCOT Center, Lake Buena Vista, Fla., is a visit to a tropical coral reef deep under the ocean....
Design of Wharf Facilities, Guam, M.I., to Accommodate Difficult Site Conditions
A wharf facility currently under construction in Guam, Mariana Islands, for the U. S. Navy utilizes precast concrete box caisson construction to satisfy difficult site conditions. To reduce...
The Application of Computer Simulation in the Design of Marine Terminals and the Scheduling of Ship Traffic
This paper describes a software package which simulates the operations of marine terminals. The computer programs were designed to assess the effectiveness of the available design alternatives...
Terminal 18 Entry Facility?Port of Seattle
This paper presents a successful approach that was used in the planning, design, permit coordination, and expansion of the entry/exit facilities at Terminals 18 and 20 at the Port of Seattle....
Designing Marinas to Mitigate Impacts
The John Wayne Marina was permitted for construction only after certain design features were altered to accomodate major biological and water quality concerns. The moorage basin was relocated...
Marina Design and Environmental Concern
Research initiated by a Florida Cabinet Resolution of August 6, 1974, has generated two models for the evaluation of the impact of marina development on coastal waters. One, a complex...
Marina Flushing and Sedimentation
The paper discusses a one-dimensional circulation model for the marina. Tides are modeled as long waves and are assumed to be much longer than the marina. This circulation model is coupled...
Perforated Wave Barriers in Small Boat Piers
Perforated breakwaters can be used to reduce the energy and the height of waves entering small boat harbors. By not extending the breakwater to the bottom interference with littoral drift...
Water Use Planning�Boston Harbor
This paper establishes a methodology for harbor planning based on comprehensively evaluating the water resource, categorizing the vessels which use the harbor, and prioritizing locational...
Ship Wave Prediction for Port and Channel Design
Several laboratory and field investigations of ship-generated waves have been conducted during the past twenty-five years. Typically, for a given ship, reported data consists of the height...
Navigation Channel Design for Safe and Efficient Ship Transit
The U. S. Army Engineer Waterways Experiment Station (WES) recently conducted a hydraulic model investigation of the western portion of Cleveland Harbor, Ohio. This study provided data...
Los Angeles and Long Beach Harbors Tidal Circulation Study
Expansion of harbor facilities frequently involves placement of additional landfill and the deepening of channels and mooring areas. A numerical tidal circulation model was used in the...
Lifeline Seismic Risk Analysis?Case Studies
These papers employ design concepts and procedures in lifeline seismic risk analysis. Two of the papers describe the seismic hazards in the northwestern United States. A systems model...
Chloramines: A Better Way?
Chlorination of drinking water has been linked to the formation of carcinogenic trihalomethanes (THMs). By adding ammonia to the water, the chlorine becomes chloramines which don't...
Tallying Water Resources Goals
Federal water resources planning philosophy has undergone a lengthy evolution with a number of refinements in the past decade to encompass environmental laws and the political philosophy...
Treating Sewage in One Tank
A sequencing batch reactor (SBR) was the answer to a sewage problem that was holding up community development in Poolesville, MD. Poolesville was one of the first municipalities in the...
